The sum of two numbers is 86.86. if twicetwice the smaller number is subtracted from the larger​ number, the result is 5.5. find the two numbers.

Respuesta :

The way you have this typed is very confusing.  You need to find 2 equations to solve for these 2 unknowns.  The first is the sum of the 2 unknowns set to equal 86: x + y = 86.  The second is y - 2x = 5 (I am defining y to be the larger of the 2 numbers here).  Solve the first equation for y:  y = 86-x.  Now sub that in for y in the second equation: 86-x-2x=5  and -3x = -81 and x = 27.  27 + y = 86, therefore, y must equal 59
